T-UGOm is a 2D/3D ocean dynamics numerical model based on unstructured meshes. Its main distinctive features are:

• multi-discretisation capabilities (mostly LGP0, LGP1, ^NCP1, LGP2, continuous and discontinuous)
• Finite volume and finite elements schemes
• explicit/semi-implicit tunable
• Time step dynamical local sub-cycling
• embedded 2D/3D spectral solver for tides

It is developed in C/C++, and provides(domain partion) MPI and OpenMP parallel optimisation. Sources management is based on Mercurial distributed version control system.

It is part of the Sirocco service, labeled and supported by INSU (Institut National des Sciencs de l'Univers).

Download

T-UGOm is available through the Mercurial depot at https://hg.legos.obs-mip.fr/tugo. See foolowing instructions for installation and compiling.

We occasionally provide tar ball distribution archive. Latest release of T-UGOm (4.1.0, 15/05/2015) is available here .

Instruction for T-UGOm installation

Pre-requisite

First the poc-solver library must be installed and compiled. see http://www.legos.obs-mip.fr/recherches/equipes/ecola/outils-produits/poc-solvers.

Needed packages:

• gsl (Gnu Science Library), NetCDF
• gtk 2.0

Instructions for depot installation and update

At first installation, you need to clone the depot by using in a local directory: 

tugo-depot> hg clone https://hg.legos.obs-mip.fr/tugo .

Autotools suite is necessary to install the local depot. First initialize the "configure" command :

tugo-depot> aclocal

tugo-depot> autoreconf -si

Latter on, you can follow T-UGOm developments and fixing by routinely updating the depot:

tugo-depot> hg pull https://hg.legos.obs-mip.fr/tugo

tugo-depot> hg update

After depot update, you will need to re-compile (see next section).

Instructions for compiling

T-UGOwith can be compiled in various optional modes, it is highly recommended to dedicate a specific compiling directory for each of them need by the user. The following command will generate a Makefile using the -g option for compiling, hence enabling debugging or step-by-step execution in a development interface such as kdevelop:

tugo-compiling> /.../tugo-depot/configure --with-debug --prefix=/.../tugo-compiling

The following command will generate a standard Makefile using the -O3 option for compiling, hence enabling an optimized code:

tugo-compiling> /.../tugo-depot/configure --prefix=/.../tugo-compiling

Once the Makefile has been generated, you can compile and install T-UGOm:

tugo-compiling> make -j XXX

tugo-compiling> make install

Using T-UGOm

Documentation and manuals for users and developers are slowly building. We are progressively feeding a WIKI site (TRAC), unfortunately not available at the moment for non-LEGOS users (external WIKI server should be implemented at LEGOS next fall). WIKI site can be found at : http://srv-ecola:8080/TRAC-TUGO/wiki .

Meanwhile some older documents are available:

Input parameters handling

User manual (to do...)

Developers documentations (PDF, to do...)

On-going developments:

• ocean wave interactions with circulation (C. Mayet, Phd)
• 2D non-hydrostatic
• 3D baroclinic spectral solver (F. Lyard, Y. Soufflet)
• Semi-Lagrangian advection mode
• 3D FV baroclinic  time-stepping solver

some recent milestones can be found in FES2012 development pages. More details in T-UGom WIKI.
